I recently tryed to put my 9800GTs in SLI and for some reason whenever there in SLI i get tearing and sometimes the hole screen will go red for about 3 seconds. The screen only go's red if i have an explosion effect close by my character. I have tryed the graphics cards by themselves i've also tryed them in diffrent slots the problem only accurse if there in SLI with each other. I tryed like 5 diffrent nvidia driver versions and none of them fix the problem. Any help would be greatly appreciated.

I reread your post and noticed you said while in game. So i played fallout 3 and noticed the GPU reachs 70C easy and the drivers only increase the fan to 50% so they stay around 70C. Also i played fallout 3 in window mode and i didn't get any tearing but the game did lag alot plus now my screen flickers.
They work fine by themselves if there in SLI they have major issues rendering just about anything. When not in SLI or when only one card is installed they work fine. Seeing as how my issue is only when there in SLI i'm thinking the SLI bridge that came with my motherboard is broken. As for the clocks on GPU2 it seems that the drivers are decreasing and increaseing GPU2's clock speeds at will i don't know if this is normal for SLI. At any given time GPU2 is almost always running at 50% clock speeds i do not understand why as it would seem to defeat the purpose of haveing 2 cards installed if one runs at 50% less performance.
Its an MSI board it says in the manual that if you use only one graphics card it must be in the first PCI-E slot in order to work. So i can only test them in the PCI-E2 slot when there by them self. I have 3 PCI-E slots they have only been tested on PCI-E2 the very top PCI-E slot.
